Caption

Mars' southern hemisphere. Three-dimensional map of Mars' southern hemisphere showing its surface topography as plotted by the Mars Global Surveyor spacecraft. Colour-coding shows elevation of the surface relative to the average surface height at the equator. Yellow areas are average elevation, while red is higher, and blue to purple lower. The huge Hellas impact basin is seen at upper left. This data was recorded by the Mars Orbiter Laser Altimeter (MOLA) on board the Mars Global Surveyor spacecraft orbiting Mars. Up to 27 million measurements were made in 1998 and 1999 by timing laser pulses sent to the planet's surface. The elevation data is accurate to within 13 metres.
